Ok, now it does!

It would just take more time to saturate, but in your case, you would still get your 2,700 PPM.
Another way to look at this question is, if there was 1000ml of DW in the receiver, would the concentration be less than if there was 300ml? Seems like the amount of CLO2 gas generated depends on how much NaCLO2 & citric acid is in the reactor.
I am referencing concentrations of CLO2 to 1000ml for all my testing to eliminate one variable.

Just keep the water below boiling point!
Yes, heating the reactor makes a big difference in the time it takes to release CLO2 gas.
Yes. Just a hole small enough to release pressure, but to keep some pressure inside to avoid gas from escaping too quickly.
By the way, I forgot to mention that your idea of a small vent hole in the receiver cap must help with the concentration by keeping the escaping gas to a minimum, yet without the bang factor!
